Product Details

2.1 Key Features
Balanced Nutrition: Provides a harmonious ratio of N, P, and K, meeting the general nutritional needs of most crops during key growth stages.
High Phosphorus Content: The elevated phosphorus level (20% P₂O₅) is particularly beneficial for root development and energy transfer within the plant.
Versatility: Suitable for a broad spectrum of crops and can be applied at various growth stages.
Ease of Use: Available in granular form, making it easy to handle, store, and apply using standard farming equipment.

Improved Soil Fertility: Helps replenish essential nutrients in the soil, promoting long-term soil health and productivity.

2.2 Primary Functions and Benefits

FunctionBenefit to PlantsAgronomic Advantage
Nitrogen (N) SupplyPromotes lush, green vegetative growth and is essential for protein synthesis.Ensures healthy leaf and stem development, leading to a strong photosynthetic foundation.
Phosphorus (P) SupplyCritical for root development, energy transfer (ATP), flowering, and fruiting.Enhances root system establishment, improves flower formation, and increases fruit set.
Potassium (K) SupplyRegulates water uptake, enzyme activation, and improves overall plant vigor.Increases drought tolerance, disease resistance, and enhances fruit quality and shelf life.
Synergistic EffectThe balanced ratio ensures that no single nutrient limits plant growth, maximizing the efficiency of each element.Leads to more efficient nutrient utilization, reducing waste and improving cost-effectiveness.

2.3 Target Crops and Application Scenarios
Cereals: Wheat, corn, rice, barley - Applied as a basal fertilizer to support strong root systems and early growth, and as a top-dressing during tillering or stem elongation.
Vegetables: Tomatoes, peppers, cucumbers, potatoes - Used at planting to encourage root development and during the vegetative stage to support healthy foliage.
Fruit Trees: Citrus, apples, grapes - Applied in spring to promote flowering and fruit set, and in autumn to support root growth and nutrient storage for the next season.
General Field Crops: Suitable for soybeans, cotton, and other crops that benefit from a balanced nutrient supply.
2.4 Application Guidelines (General)
Basal Application: Apply before or during planting. Incorporate into the soil to place nutrients within the root zone. Rates typically range from 200-400 kg per hectare, depending on the crop and soil fertility.
Top-Dressing: Apply during the growing season to supplement nutrient needs. For cereals, this is often done during tillering; for vegetables, during the vegetative growth phase.
Placement: Band application near the seed or plant row can improve nutrient uptake efficiency, especially for phosphorus, which is less mobile in the soil.
Soil Testing: Always conduct a soil test to determine the specific nutrient requirements of your crop and adjust application rates accordingly.


Note: NPK15-20-15 is a reliable and widely used fertilizer that provides a solid foundation for crop nutrition. Its balanced formulation makes it a safe and effective choice for farmers seeking to improve overall crop health and productivity. By understanding the specific needs of your crops and soil conditions, you can maximize the benefits of this versatile fertilizer.
